摘要
鉴于指纹识别系统较高实时性、准确性的要求,对一种基于STM32芯片和中控光学指纹采集仪的嵌入式指纹识别系统进行了研究和实现。利用改进的Gabor滤波增强算法对指纹数据进行图像预处理后,采用指纹纹线的二值化细化中心线提取法提取图像的细节特征点,在VC++环境平台下进行仿真,结果显示系统达到了预期的效果。
In view of the fingerprint identification system has high requirements in real-time and accuracy, this article described an embedded fingerprint identification system based on the STM32 chip and the optical fingerprint sensor. It improved Gabor filter enhancement algorithms was used for fingerprint image pre-processing,it extracted minutiae by the minutiae detection template. The simulation results in the platform of VC ＋ ＋ environment show that the system has reached the desired effect.
